FISHNG'V TOOL.

Application filed January 11, 1922. Serial No. 528,383.

To all iff/0m 'it may conce/rn.'

Be it known that l, EDWARD il. Moon, a citizen of the United States, residing at Florence, in the county of Marion and State of Kansas, have invented certain new and uset'ul Improvements in Fishing` Tools, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to pishing tools for removing sucker rods and conduits from wells.

in object et' the inventiton is to provide a tool or' this character which is substantially auto-matic in attaching itseliEl to a sucker rod to permit ready removal of the rod.

Another object of the invention is to provide a tool of this character having teeth disposed inwardly thereoll and having a gravity operated jaw member adapted to urge the sucker rod toward and into engagement with the teeth.

t is also an object of the invention to provide a tool of this character having a movable jaw member adapted to practically embrace the member to be removed to cause penetration ot' said member by the teeth or' 'the tool.

It is a 'further object of the invention to prvride a tool of this character composed ot' a. number oitl sections, each may be readily disassembled when necessary, one of said sections including` a pivoted jaw member adapted to extend partially over said section, said jaw member being automatic in its operation to substantially jam the member to be removed into engagement with the teeth ot the tool upon upward pull of the tool and resistance ot the object to be removed.

lilith these and other objects in view, the invention consists in the improved construction and arrangement ot" parts to be hereinat'tcr more particularly described, iully claimed and illustrated in the accompanying drawings, in which y Figure l is a longitudinal sectional view of a fishing tool constructed in accordance with an embodiment oit the invention;

Figure 2 is a detailed view of the jaw member;

Figure 3 is a perspective view of the bearing member;

Figure 4l is a transverse sectional view of the structure shown'in Figure l, the jaw member being removed; and

Figure 5 is a fragmentary plan view oi another form of connecting the jaw member kto the body member.

lReferring to tli e.clrawings, 5 designates the cap or top section of the tool, the inner tace and walls of the cap being threaded, while projecting from the top of the `cap centrally thereof is a shank 6 having a collar 7, the portion of the shank above the collar being threaded for engagement with any suitable means to apply or remove the tool. The second section ol the tool comprises a sleeve 8 which is enteriorly threaded, one end of said sleeve being disposed within the cap, while the opposite end is threaded for engagement with an internally threaded collar or coupling 9. The coupling 9 has an inwardly projecting annular protuberance 9, said protuber'ance being disposed at the central portion and inwardly of the coupling to provide a stop for the sleeve 8 andbody member to be hereinafter described, to hold said braces in spaced relation to each other and prevent interference with the operation of the device. By this means, the length of the tool can be regulated so as to permit the end oil the broken sucker rod to extend a considerable distance within the tool before the gripping operation takes place, to allow for a considerable amount of outward movement ot' the rod before the same is firmly secured within the tool.

In connection with the tool, abody member l0 is provided, saidbody member havf ing an eccentric bore l1, or in other -words, a longitudinal bore which is disposed nearer one side ot the body member than the opposite side. The inner wall or tace out the bore is substantially flared trom a point adjacent the intern'i'ediate portion ol the body member to the lower end l?. oit the body member. The upper `end f1.3 oi the body member is annularly reduced to provide an annular shoulder lst, said. reduced portion being oxteriorly threaded for insertion inthe lower end oi the coupling 9, the end ot said coupling being adapted to engage the shoulder 14. By the use of the eccentric bore, a relatively wide lportion l5 and narrow portion 16 are provided. A series of zgripping teeth 17 are provided inwardly of the end portion 13 of the body member and adjacent the narrow portion lo thereof, said teeth extending onlyr halt- Way around the .inner wall. the bore. The teeth 1T are also inclined toward the end 13 ot the body member, or in other Words iq'nvardly, so that movement oi' an object Within the body member, toward the end l2, when engaged with the teeth 17 will cause the teeth to penetrate said object.

The portion 15 of the body member is provided with a threaded opening 18 adapted to receive the threaded shank of a pin or bearing member 19, said shank including a head 2() which is rounded and provided with a recess 21 in one tace thereof, said. recess being substantially semi-circular and extending laterally of the head. A jaw member :22 is used, the jaw having a convex top to increase the Weight of the aw. The diameter of the jaw is less than the diameter of the bore 11. An extension or bearing member 2B projects from the edge ot said dise, While a slot or opening` 2i inovided in the extension Q3, the slot being adapted to re eive the head ot' the pin 19, While the portion of the pintle adjacent the slot is intended to enter the recess 21 oi the pin. The portion of the disc diametri-cally opposite the pintle and slot is provided with a substantially V-shaped recess 25, the edges ot' said recess being sharpened to provide teeth :26 adapted to substantially cooperate with the teeth 17 of the body member.

In Figure 5, another form of connection for the disc to the body member is shown. This form consists oi' a pair of ears 27 1which may )e threaded into the body member or formed integral With said body member, the ears being provided 1Nita registering openings. rIlle edges of the ears adjacent the bore are rounded so as 'to tacilitate movement of the disc. T he disc LB in this ornrot the invention is provided with a projection or lug 29, the extremity of said lug being extended upwardly to provide a stop 30. The lug` 29 is intended to be disposed between the ears, the pin being passed through the registering openings of the ears and the lug to pivotally connect the disc to said body member.

In the use ot the device, the shank 6 is coupled. to a rod and inserted in the iveli. The flared portion of the bore 1l permits the tool to guide the end ot the broken sucker rod inwardly ot the body member, the

broken end of the rod passing beyond the end 13 ot the body member and in through the sleeve 8, so as to allow for slipping .vhen the tool is pulled upwardly. Also, upon inward movement of the broken sucker rod, the same comes in contact with the jaw member 22 and urges the same upwardly above the end 13 of the body member, the rod thereby entering the recess 25. Il pon reverse or upward movement of the tool, the sucker rod will naturally resist, thereby urging the jaw member downwardly and substantially inwardly of the bore 11, causing; the teeth 17, as well as the teeth 2G of the jaw member to bite into the surface of the sucker rod whereby up-4 ward movement of the tool may be continued to ei'iiciently remove the broken sucker rod from the Well.

From the foregoing it will be readily seen that this invention provides a novel form ot tool for use in Wells, to efliciently remove the sucker rod Without loss of time and Without inconvenience to the operator, the gripping operation of the sucker rod Within the tool being automatic in view of the novel formation of the j avv members and the particular position of the teeth 17. In addition to this, in view of the various sections of the tool it may be readily removed and disassembled if necessary, and at the same time this feature permits lengthening ot the tool to permit the broken end of the sucker rod to enter the tool a considerable distance before the movement of the tool is reversed, so as to prevent accidental disengagement ot' the rod from the tool.

Wfhat is claimed is A fishing tool embodying a tubular body member having one end thereof reduced and exteriorly threaded, the end face of said reduced portion having a threaded opening, a bearing block having a threaded stein, said stem being adapted to extend into the opening, one face oi' the block having a bearing` groove, a clamping plate having an extension, the outer edge of the extension being rounded, said extension having an opening for the reception ot' the bearing block, the groove of said bearing block being` adapted to receive the rounded edge of the extension.

In testin'ioi'iy whereof I hereunto aiix mv signature.

EDWARD J. MUC/il.
